ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to portable telephone sets and data communication adaptors and, more particularly to a portable telephone set and a data communication adaptor used to build a mobile communication system that includes an information processing device.
Recently, portable telephone sets are being used not only for telephone communication but also used in combination with an information processing device for mobile communication. Accordingly, it is required that a portable telephone set be useful to build a mobile communication system.
2. Description of the Related Art
FIGS. 1A and 1B
show a portable telephone set
10
according to the related art and how a mobile communication system is built using the portable telephone set
10
.
The portable telephone set
10
has a connector
10
a
at the bottom thereof connectable to a connector of a cable.
FIG. 1A
shows a mobile communication system

not having a built-in data communication adaptor. The mobile communication system
30
is built using the information processing device
20
, a cable
40
with connectors and a data communication adaptor
50
. A connector
40
a
at an end of the cable
40
is connected to the connector
10
a
of the portable telephone set
10
. A connector
40
b
at the other end of the cable
40
is connected to a connector
50
a
at an end of the data communication adaptor
50
. The data communication adaptor
50
is inserted into a data communication adaptor accommodating unit
20
a
of the information processing device
20
. A connector
50
b
at the other end of the data communication adaptor
50
is connected to a connector
20

at the rear end of the data communication adaptor accommodating unit
20
a.
Normally, the data communication adaptor
50
is inserted into the data communication adaptor
20
a
of the information processing device
20
.
FIG. 1B
shows how a mobile communication system
30
A is built using an information processing device
20
A having a built-in data communication adaptor. The information processing device
20
A has a built-in data communication adaptor
60
. The mobile communication system
30
A is built using the information processing device
20
A, the cable
40
with the connectors. The connector
40
a
at an end of the cable
40
is connected to the connector
10
a
of the portable telephone set
10
and the connector
40
b
at the other end is connected to a connector
60
a
of the data communication adaptor
60
built into the information processing device
20
A.
A user who intends to perform mobile communication carries the portable telephone set
10
with himself or herself. In addition, the user carries the information processing device
20
(
20
A) and the cable
40
in, for example, a bag. If the cable
40
connected to the information processing device
20
(
20
A) is accommodated in the bag, a intensive force is applied to the joint between the cable
40
and the information processing device
20
(
20
A), causing the joint to be damaged. For this reason, the cable
40
is disconnected from the information processing device
20
(
20
A) while being carried.
Therefore, the user may leave the cable
40
behind at home since it is comparatively small. If the cable
40
is lost, mobile communication is impossible.
Another inconvenience is that, since the cable
40
should be connected to the portable telephone set
10
as well as to the information processing device
20
(
20
A), it takes time to build a mobile communication system.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a portable telephone set and a data communication adaptor in which the aforementioned problems are eliminated.
Another and more specific object of the present invention is to provide a portable telephone set and a data communication adaptor whereby a data communication system is more readily built than according to the related art.
The aforementioned objects can be achieved by a portable telephone set comprising: a telephone set main body; and a cable accommodating portion for accommodating a cable with a connector connectable with a mobile information processing device, wherein the cable is accommodated in the cable accommodating portion such that an end of the cable is electrically connected to the telephone set main body.
Since the cable with the connector is accommodated such that an end of the cable is electrically connected to the portable telephone set, it is not necessary for a user to carry the cable with him or her. The cable is not lost by any chance. For mobile communication, the user has only to take the cable out of the cable accommodating unit and is not required to connect the cable to the portable telephone set.
The aforementioned objects can also be achieved by a portable telephone set comprising: a telephone set main body; and a flipper attached to the telephone set main body, wherein the flipper includes a cable accommodating portion for accommodating a cable with a connector connectable with a mobile information processing device, and the cable is accommodated in the cable accommodating portion such that an end of the cable is electrically connected to the telephone set main body.
It is to be appreciated that it is easier to provide the cable accommodating unit in the flipper than in telephone set main body.
The aforementioned objects can also be achieved by a portable telephone set comprising: a telephone set main body; and a flipper detachably attached to the telephone set main body, wherein the telephone set main body includes a telephone set main body connector, the flipper includes a cable accommodating portion for accommodating a cable having a first connector connectable with a mobile information processing device at one end thereof and having a second connector connectable with the telephone set main body connector, the cable is accommodated in the cable accommodating portion such that the second connector is fixedly secured to the cable accommodating portion, and the flipper is mechanically joined to the telephone set main body in a state where the second connector is connected to the telephone set main body connector.
Since the flipper is independent of the telephone set main body and detachably coupled thereto, the telephone set main body may be used for a plurality of types of portable telephone sets for users who intend to perform mobile communication using a portable information processing device.
The aforementioned objects can also be achieved by a portable telephone set comprising: a telephone set main body; and a connector to which a data communication adaptor for use in data communication when the portable telephone set is connected to a mobile information processing device is electrically connected.
By directly connecting the data communication adaptor to the portable telephone set, it is possible to perform mobile communication using a portable information processing device not having a built-in data communication adaptor.
The aforementioned objects can also be achieved by a portable telephone set comprising: a telephone set main body; and a flipper detachably attached to the telephone set main body, wherein a portion of the telephone set main body connected to the flipper is provided with a connector electrically connected to a data communication adaptor used for data communication when the portable telephone set is connected to a mobile information processing device.
By removing the flipper and connecting the data communication adaptor to the portable telephone, it is possible to perform mobile communication using a portable information processing device not having a data communication adaptor
The aforementioned objects can also be achieved by a card-like data communication adaptor used for data communication when a portable telephone set is connected to a mobile information processing device, comprising: a portable telephone set connector connectable to one of a portable telephone set a
